The original plan was to release Ark on Hulu in the US and on YouTube for the rest of the world. The good/bad news is that Ark was so successful on Hulu that the series' owners decided to release it through a distrubution company, instead of simply putting it on YouTube.

Content Media won the overseas distribution rights (they also have the rights to Riese and Booth at the End and other webseries), now it's up to them to arrange the release in other territories.
